Gemstone Treasures of Maine

Maine is known for its picturesque coastal towns, rugged terrain, and abundant wildlife. But did you know that beneath its rocky surface lies a treasure trove of precious gemstones?

From the northern tip to the southern coast, Maine boasts a rich variety of gemstones that are highly prized for their color, clarity, and rarity.

Tourmaline

One of the most popular gemstones found in Maine is tourmaline. Known for its wide range of colors and high-quality gem-grade specimens, tourmaline is a type of crystal that forms in pegmatite veins.

Pegmatite is a type of igneous rock that forms from cooling magma, and it tends to contain large crystals of minerals like quartz, mica, and feldspar. Watermelon tourmaline is perhaps the most well-known type of tourmaline found in Maine, with its distinctive green and pink hues.

Maine tourmaline is highly sought after for its unique coloration and gem-quality clarity. The best places to find tourmaline in Maine are in the areas around Mount Mica and the Newry Mining District.

Beryl

Another popular gemstone found in Maine is beryl.

Beryl is a mineral that comes in a variety of colors, including green (emeralds), pink (morganite), yellow (heliodor), and blue (aquamarine and blue-green beryl).

In Maine, beryl tends to form in large crystals, with some specimens reaching several feet in diameter. The Rose of Maine is a large, faceted piece of pink beryl that was discovered in 1910 and now resides in the Smithsonian Museum.

It is one of the largest and most well-known beryl specimens in the world.

Topaz

While topaz is not as commonly found in Maine as tourmaline or beryl, it is still a valuable gemstone that can be found in certain areas. Blue topaz is the most desirable type of topaz, and it is found in the Oxford and Sagadahoc Counties of Maine.

Clear topaz is also found in Maine, although it is not as valuable as the blue variety.

Topaz can be found in granite formations and in the sand and gravel of riverbeds.

Kyanite

Kyanite is a blue bladed crystal that is found in metamorphic stones like mica-schist.

Kyanite is highly valued for its hardness and its ability to withstand high temperatures, making it useful in a range of industrial applications.

The best places to find kyanite in Maine are in Cumberland County and Franklin County.

Staurolite

Staurolite is a reddish-brown neosilicate mineral that forms cruciform penetration twinning, giving it a distinctive shape.

Staurolite is found in metamorphic stones like mica-schist, and it is most commonly found in the southwestern portion of the state, particularly in Cumberland County, Augusta, and Knox County.

Skarn Minerals

In addition to gemstones, Maine is also known for its skarn minerals, which are formed when minerals and magma interact in the midst of metamorphism. Two of the most popular skarn minerals found in Maine are vesuvianite and garnet.

Vesuvianite

Vesuvianite is a greenish crystal formation that has short pyramids and long prisms. It is found in limestone formations in Cumberland County and York County.

Vesuvianite is highly valued for its color and its propensity for producing brilliant faceted stones.

Garnet

Garnet is a type of mineral that comes in a range of colors, including almandine garnet (red to reddish-brown) and spessartine garnet (orange to orange-red). In Maine, garnet is found in the Ragged Jack Mountains, the Edgecomb Quarry, and Lincoln County and Byron.

The abundance and variety of gemstones and minerals found in Maine make it an ideal destination for rockhounds and gem enthusiasts. From the rare and highly valued tourmaline to the brilliant and colorful garnet, Maine’s gemstone treasures are waiting to be discovered.

Amethyst

Amethyst is a purple variety of quartz that is prized for its color and its crystalline structure. In Maine, amethyst can be found in the Oxford County region.

While natural amethyst is often a pale purple color, most commercial amethyst is heat treated to enhance its color. Heat treatment converts the iron in the crystal to ferric iron, which causes the purple color to become more pronounced.

Amethyst can also be treated to produce other varieties of quartz, such as citrine (yellow) and prasiolite (green).

Amethyst is often associated with spiritual and healing practices, and it is believed to help calm the mind and balance the emotions. Rose

It is often multicolored, with bands of red, yellow, brown, and green.

Jasper is valued for its hardness and durability, and it has been used for centuries in jewelry, carving, and decorative objects. Red jasper is often associated with courage and protection, while yellow jasper is associated with mental clarity and grounding.

Agate

Agate is another type of chalcedony that is prized for its unique banding patterns. Cryptocrystalline silica forms agate, which can be found in a variety of colors and patterns.
